To all whom itmay concern:

Be it known that LvMoRRis S. WRIGHT, of the city and county of Worcester'and State of Massachusetts, have invented certain new and useful Improvements in Reed or Pipe Organs; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figure l represents a vertical transverse section through so much of a reed-organ as is necessary to illustrate my improvements. Fig. 2 is a vertical longitudinal section through the secondary channel-board, taken on line a, Fig. l, looking in the direction indicated by the arrow. Fig. 3 represents, upon an en larged scale, a vertical longitudinal section through part of one 0f the tone-chambers, taken on line Z), Fig. l, looking in the direction of the arrow and showing a front view of several of the separate secondary pneumatics and the eut-off valves thereof, all the following figures also being upon the same enlarged scale. Fig. 4 is a horizontal section through part of the secondary channel-board, taken on line c, Fig. l, looking down, as shown by the arrow and showing some of the flexible pneumatic cut-off valves of the tone-chamber hereinafter described. Fig. 5 is a horizontal section through a part of the secondary chanv nel-board j ust above the primary pneumatics,

showing a` plan of some of said pneumatics. Fig. 6 is a similar sectional view to Fig. 1 of one of the tone-chambers andpart of the secondary channel-board upon an enlarged scale. Fig. 7 is asimilar view to Fig. 6, showing certain modifications inthe construction, which will be hereinafter described. Fig. 8 represents the front end of one of the tone-chambers with the end of an ordinary organ-pipe applied thereto, and Figs. 9 and 10 are horizontal sections taken on lines a and a2, respectively, Fig. 1.

The object of my invention is to effect irnprovements in the reed or pipe organs covered by my United States Patent No. 509,506, dated November 28, 1898, vwhereby the capacity in variety of tones of said instrument may be increased without increasing its size over the old style of instruments; and it consists in combining with the instrument a double primary pneumatic system connected with each secondary pneumatic in the tone-chambers, each tone-chamber containing a serles of separate secondary pneumatic and reed valves, g one of each for each pair of primary pneumatics and each reed, the channel-board of said tone-chamber being also provided with two double channels and cut-off valves for each secondary pneumatic controlled by two stops for each tone-chamber, as will be hereinafter more fully set forth.

In order that others skilled in the art to which my said invention appertains may better understand the nature and purpose thereof, I will now proceed to describe it more in detail.

Referring to the drawings, A represents the primary channel-board, upon which is mounted the double rows or series of pri-mary pneumatics B C, the same being arranged in pairs in this instance transversely thereon and connected by means of vertical Wire stems B C with the double cut-oif or switch valves D D2 and E E2 of the Wind-chests D and E, respectively. In this instance said primary channel-board A has two branchesA A2, both extending vertically for a short distance, and then horizontally to receive and support the wind-chests F G,which are connected, as usual, with the upper and lower banks of keys H and I, respectively.- Said wind-chestsF Gare also connected with the primary pneumatics by means of the primary channels A3 A3 in the aforesaid primary channelboard and its branches. The wind-chests D E and tonechambers J J are in this instance detaehably fastened by means of screws cl to the secondary channel-board K. Said wind-chests areV each provided with a separate channel D3 E3, respectively', also, with the air-outlets e e' and f f respectively, which are opened and closed by the cut-off or switch valves D' D2 and E E2, previously mentioned, when the primary pneumatics are operated'as hereinafter described. Said separate wind-chest channels D3 G3 connect with separate channels K K2 in the secondary channel-board K, which in turn respectively connect with two separate double channels g g and h h, formed in the top and bottom edges of the tone-chamber channelboard J of tone-chamber J, thereby, as will be seen, forming double separate connections between each transverse pair of primary pneumatics B C and each separate secondary pneumatic L. Over the central outlets of each double channel h h g g in the tone-chamber channel-board J is iitted a flexible pneumatie cut-off valve t', and over said flexible valves are in turn arranged the long hinged cut-01T valves M M', which are in practice mechanically connected with the stops N N of the instrument. As the mechanism for obtaining said connections between said stops and cut-off valves is old and well understood and does not constitute a part of my invention it is deemed unnecessary to illustrate or describe the same. Each tone-chamber, as will be observed by the above-described construction, is provided with two stops for each secondary pneumatic L instead of one, as usual. Therefore each of said secondary pneumatics being capable of operation from two separate primary pneumatics, and said primary pneumatics being in turn operated, one from one of the keys oi" one bank or manual and the other from one of the keys of the other bank or manual, it is obvious that the same reed of each pair of primary pneumatics may be operated from either manual.

In case it is desired to use a certain stop operating a certain tone on both manuals it is necessary by the old method to have two separate stops for each manual, whereas in my improved instrument one stop and reed answers for both manuals. One reed or tone being thus connected with both manuals the same may be operated by either at will. By this construction it is unnecessary to have a coupler connection between the manuals, as usual, as the full organ may be played from either manual.

As is well known, different organista have dierent ideas as to where they want the different stops arranged, both as regards the swell manual and the great manualas, for instance, one may want a flute tone in the swell manual, while another may want it in the great manual. If they want the iiute tone in both manuals of an old-style instrument, it is obvious that the capacity of the instrument must necessarily be decreased as to variety of toneswith the same size of instrument. By my instrument both may be accommodated, as one and the same flute tone or any other desired tone may be played, as aforesaid, from either manual without decreasing the variety of tones or increasing the instrument above its usual size.

In this instance the keys II of the upper bank or manual connect with and operate the primary pneumatics B and the keys I of the lower bank or manual connect with and operate the primary pneumatics C, While the upper stopsN are adapted in practice for ioperating the top cut-off valves M and the lower stops N the bottom cut-off valves M; but I do not limit myself to said arrangement. I have also in this instance shown the instrument as being operated by air-pressure; but

since it may in practice be operated by airsuction I do not limit myself thereto.

In operation it will be understood that the various wind-chests and tone-chambers are all supplied with air under equal pressure from the usual source of supply. Therefore when the cut-off valves M M are open, an equal pressure existing at each side of the secondary pneumatics, an equilibrium thereof is maintained and they remain stationary, which is their normal positions, with their re spective reed-valves O closed, as is shown in the drawings. They thus remain until one ofthe keys-H, forinstance-is pressed down. This causes its wind chest valve Il to be opened and its primary pneumatic B to be raised to close the wind chest outlet e and open the channel-outlet c', thereby permitting the air back of the secondary pneumatic to escape through the various channels and said outlet e. Said removal of the air-pressure from the back of said secondary pneu matic permits the latter to be forced back by the air-pressure in the tone-chamber, and by said operation the reed-valve is also drawn back through the wire connection O and opened, thereby causing the reed P or pipe Q to speak, according to which is combined with the instrument.

In order to economize in space, I have arranged each alternate transverse pair of primary pneumatics above the level of the adjoining pairs-one pair, in this instance, bein g arranged to come on, a level with the top of the primary channel-board and the ones next thereto a little above the same, as is shown in Figs. l and 5, thereby admitting of said pneumatics being placed close together,- only suflicient longitudinal space being necessary between them to receive the wire stems B C.

It is obvious from the foregoing description that while increasing the capacity of the in# strument in the way of tone eii'ects I have not increased the instrument above the usual length of such instruments. The cost thereof is also not materially increased over the old style of instruments. It will also be apparent that the capabilities ol such an instrunient may be further augmented by employing an additional number of primary pneumatics in each transverse row and making the other parts thereof to correspond therewith in practice without departing from the principle of my invention. I therefore reserve the right to use more than two primary pneumatics, cut-olf valves, and channels with each secondary pneumatic, il' desired.

In Fig. 7 I have shown a modification of the tone-chamber and adjacent parts. In this instance, instead of employing one secondary pneumatic Il for each pair el? double channels g g 7L 7L in the tone-chamber channel-board J and connected with the reed or pipe valve O by means ci one wire connection O', as previously described, I have shown two separate secondary pneumatics Il I/one at the top and the other at the bot ICG tom of the tone-chamber-one for each double channel g g h h and independently connected by means of arms L2 L2 and wires L3 L3 with one of the reed or pipe valves O. As will be observed, the same result may be 0btained by this construction as by that first described and shown by the other figures of the drawings, and since the same principle is carried out by both I reserve the right to use either construction in practice.

I-Iaving described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. In a reed' or pipe organ, the primary channel-board, having branches upon which are mounted the key wind-chests and their valves, with which the keys for playing the instrument are connected, said channelboard and its branches, also having a separate channel to each primary pneumatic; said primary pneumatics, arranged in pairs on said primary channel-board; the secondary channel-board and double wind-chest, having double, connecting-channels, one for each primary pneumatic of each pair, and two, double, cut-oft or switch valves, for each double wind-chest, each separately connected with the primary pneumatics of each pair; in combination with the tone-chambers, each containing a series of separate, secondary pneumatics and reed-valves, one of each for each pair of primary pneumatics and each reed or pipe-the channel-board of each of said tone-chambers being also provided with two, double channels and cut-oft valves for each secondary pneumatic, controlled by two stops for eac-h tone-chamber, substantially as and for the purpose set forth.
